Same goes for open trailers.
I was kicking around the idea of picking an open trailer but they are running $5k now.
I found the receipt for my old one which was $1200 in 2002
Not sure where you are looking but they are under 3 grand around here for an 18 foot steel deck deluxe trailer with sealed lighting, etc., slide out ramps.
I had a one off custom open trailer built for me this time last year. 23 foot, steel deck, split tilt deck, with fixed deck on the front( and ramps) to load my golf cart separately.
That even included sweet mag wheels for it. Paid only 5 for it.
